Locomotive is a simple but powerful CMS based on liquid templates and mongodb database. Locomotive CMS does not use a classic sql database such as mysql or postgresql but rather a nosql database named mongodb.

Locomotive has been tested it with both ruby 1.8.7 (2009-06-12 patchlevel 174) and ruby 1.9.2.p0 which are two of ruby versions Heroku supports. Locomotive is in beta but already used in production with success.
